Hacking the LCA registration process for fun and, er, fun
With the way tickets went for Linux
Conf AU this year gone, and getting paid today, I decided to get
my registration in early. Once again I noted they had continued the
fine tradition of having a random silly message per registrant. Once
again I decided to hack it to make it say what I wanted it to say.
Needless to say they raised the bar this year. Up until 2007 it was just a hidden field in the form. In 2008 they added a checksum - this delayed me a good five minutes while I worked out how they'd generated it. This year they've upped the ante, including both a different checksum and adding a salt to it. Another five minute's playing with bash revealed the exact combination of timestamp, delimiter, and phrase necessary to get a correct checksum. I am also made of cheese.
Naturally, don't bother emailing
me to find out how I did it; the fun is in the discovery!
